If youve never used a Visibook before, youll find that it contains several hundred illustrations, with comparatively little text. It presents essential tasks, breaks them down into steps, then walks you through them with illustrations. What youll learn Youll learn how to use HTML to create a solid, attractive Web site thats easy to navigate. Youll also learn how to upload it to a Web server. You wont become an expert in Web publishingthat takes practice and real- world experience. But you will learn the fundamentals of site-building, and get a good foundation on which to build professional-level skills. Additional resources for acquiring expert- level HTML and JavaScript skills are found at the end of this book. How youll learn it This book has five sections: HTML Basics, Layout & Navigation, Interactivity, Advanced Layout, and Practical JavaScript. At the end of each task and section are practice exercises. Dont worry if you cant work through the whole book in a day or two. Take your time, and try to do the practice. You can check your work against examples posted on the Web. Follow the steps ! See the results Download other Visibooks for free at www.visibooks.com 2 Before you begin Before you begin, its important that you know Windows well. A working knowledge of Windows makes it much easier to learn HTML and JavaScript. You should be familiar with: • How directories work • Windows Explorer • Basic word processing Make sure you can perform the following tasks: • Create a folder on your computers hard drive • Create a folder within a folder • Copy a paragraph from one document and paste it into another. If you have trouble doing this, set aside a couple of hours to learn Windows basics. Have a friend or co-worker who is proficient with computers walk you through Windows Explorer, creating folders and becoming familiar with file extensions. You should also practice using the Cut, Copy, and Paste commands in a standard word processing program. When you can do these things on your own, youre ready to learn HTML and JavaScript.
